Lime Production Industry Profile
Limestone is converted into lime through heating in a kiln a process known as calcination. When limestone is subjected to high temperatures it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2).

Computation of steady state thermochemistry in rotary
The flame temperatures in rotary kilns may exceed 2000 K and the processes occurring are due to the heat exchange from the hot gas phase to the bed material. The bed will then undergo changes due to its absorption of heat a conventional sequence being drying with subsequent heating followed by calcining or more complex chemical reactions.
